JSC Form 1830 Report of Medical Examination

The Neutral Buoyancy Laboratory (NBL) at NASA Johnson Space Center enables astronauts and mission personnel to rehearse on‑orbit tasks and resolve operational challenges in a controlled underwater environment. As part of its safety and readiness processes, NASA requires individuals participating in NBL diving activities to submit a completed JSC Form 1830- Report of Medical Examination, which documents medical fitness to dive and supports NASA’s ability to validate physical capability for NBL operations.
